Leap, and the net will appear.
Problems are not stop signs, they are guidelines.
The dog that trots about finds a bone.
By failing to prepare, you are preparing to fail.
What you do today can improve all your tomorrows.
After a storm comes a calm.
If you think you can do it, you can.
The wise does at once what the fool does at last.
Be kind whenever possible. It is always possible.
Either you run the day or the day runs you.
I have taught history on the high school and college levels, and am or have been a lecturer at the Smithsonian, The National Institutes of Health, and numerous colleges and universities, mostly on science fiction and technology subjects.
